摘　　要：目的:探讨CT检查在胰头-壶腹癌累及周围结构与胰头周围肿块病变鉴别诊断中的价值。方法:回顾性分析21例经临床病理证实的胰头周围肿块病变的CT表现,与同期17例病理证实的胰头-壶腹癌累及周围结构的CT表现对比。结果:胰头-壶腹癌累及周围结构与胰头周围肿块病变的病例,在胰头的形态、胰管及胆管扩张、胰腺体尾部萎缩等方面有较大差异。结论:CT检查有助于鉴别胰头周围肿块病变与胰头-壶腹癌累及周围结构。Objective： To explore the value of CT in diffirential diagnosis of pancreatic head carcinoma and cancer around ampulla invading peripancreatic structures from ,peripancreatic lesions invading head of pancreas. Methods： The fin- dings of CT in 21 patients with documented peripancreatic lesions invading head of pancreas and those of CT in 17 patients with pancreatic head carcinoma or cancer around ampulla invading per]pancreatic structures in the same period were retro- spectively compared and analyzed. Results： There was significant difference in the shape of of pancreatic head, dilation of pancreatic duct and bile duct and atrophy of pancreatic body and tail between the patients with pancreatic head and ampulla carcinoma invading peripancreatic structures and those with peripancreatic lesions invading head of pancreas. Conclusion：CT is useful in the differential diagnosis of pancreatic head carcinoma or cancer around ampulla invading peripancreatic struc- tures from peripancreatic lesions invading head of pancreas.
